Yeah just black. Black hair turning red is common, called rusting or sun bleaching, so he's not a tortoiseshell or anything. Black hair turning a bit grey (either the tips or the base/undercoat) or having some white hairs is also common. Especially with long hairs.
Your cat's fur is normal, that's what a tabby typically looks like (the second fur photo), and she has a broken mackerel pattern, not spotted. The kitten (I presume? First fur photo) looks to be a smoke, which is less common but not unusual. It's not indicative of Egyptian Maus though and I...
Those aren't rosettes, he looks like a broken mackerel tabby, or possibly spotted from the looks of one photo even though the back stripe is solid, not sure. Either way, they're not rosettes. He's a Domestic Shorthair, black (usually called brown) tabby with white.
I don't think that has anything to do with the tabby genes darkening the white body. There are loads and loads of lynx points with white or near-white bodies, just the same as solid points. Same how there are loads of solid pointed cats with dark bodies for the reasons I already mentioned.
You're saying lynx point means there's less contrast between the body and points than solid pointed cats? Do you have sources for that? I've never heard of that. It's either temperature or genes (mink, sepia) that affect the amount of contrast in the body.
So then both parents are the supposed Egyptian Mau and Persian mix? Possible I suppose, but highly unlikely and the kitten doesn't really look the part.
Oh my original comment was supposed to have mentioned shaded as well, like StefanZ said, but looks like my addition wasn't saved before I...
Do you have any proof one if her parents is an Egyptian Mau? You're already skeptical about the Persian, it's likely the seller was lying about both breeds. How is she inbred if her parents are two different breeds?
She's most likely a domestic shorthair (and without papers is considered such)...
Yep, she's a tabby tortoiseshell (or torbie if you want to shorten it). The back stripe and belly spots are normal for all tabby patterns. Looks like she's mackerel (due to the stripes) and just has a lot of ticking/agouti hairs, but it'll be more obvious when she's got her adult coat.
